Tonygreens Tortured Beans/ 2021 Karma Genetics Collaboration
Stone Sour
((Lemon Tree x Sour D) x GG4) x Sour Diesel Bx4

Stone Sour has been in the works for over a year. Tonygreen hit our GG4 mom with Lemontini pollen from Karma and did a selection run to select our winning mom. All of these were extraordinary so we will look to remake the “Gluetini” for a future release. Tonygreen’s winning Gluetini mom was hit with our killer Sour D Bx4 male. The results are truly mind-bending!

A Deep rich black Cuban coffee base partners with a thick, rich, dry, dark chocolate flavor that is riding the aggressive, soft tissue offending, face-melting Sowah that is sharp and wicked potent. She takes you to the top with an eyes wide open ride and then blasts through the roof like the end of Willy Wonka chocolate factory. The challenge with these is a small seed size from the GG4 mom but the rewards are tremendous and what I feel is a world-class seed line. This is my first empty jar sitting next to Sour Diesel Bx4, GG4, Headbanger, and GG4 RIL.

Flowering Time: 63-77 days
